What is the BCG Vaccine (Vaccine for Tuberculosis)?

The BCG vaccine in Australia is used to protect against severe forms of tuberculosis (TB), a serious infectious disease that most commonly affects the lungs. While TB incidence in Australia is low, vaccination remains important for individuals at increased risk of exposure. The BCG (Bacille Calmette-Guérin) vaccine has been used globally for many decades and is recognised for its role in preventing severe TB disease, particularly in infants and young children.

How the BCG Vaccine Works
